**(g)**Any repair, alteration or modification made to the Aircraft and any replacement parts, including any replacement engine, installed thereon in the course of repairing or maintaining
the Aircraft, shall be deemed an accession, and title thereto shall be immediately vested in Lessor without cost or expense to Lessor, except with respect to a temporary loaner engine, APU or part installed on the Aircraft during the period of
maintenance or repair of the original engine, APU or part required by this Agreement, and provided such loaner engine, APU or part is removed and the original engine, APU or part (or any accession as may be permitted hereby) is reinstalled promptly
on the completion of such repair or maintenance, but, if reasonably practicable, no later than the first to occur of (i) 6 months after the applicable removal or (ii) termination of this Agreement in accordance with its terms; and if
reinstallation is not reasonably practicable by such time, then Lessee shall make reasonable accommodations for such reinstallation. Reinstallation of any original engine, APU or part (or any accession permitted hereby) shall be accomplished to
allow the Aircraft to conform with the Return Conditions on the Return Date. Otherwise, Lessee will not modify the Aircraft or affix or remove any accessory to the Aircraft leased hereunder, without the consent of Lessor. Lessee may use
Lessee’s existing Ground Support Equipment (**“GSE”**) and Spare Parts (“**Spares”**) in support of the Aircraft during the Lease Term, which shall remain the property of Lessee until installed on the Aircraft, at
which time such GSE and Spares shall be deemed an accession in accordance with this subsection of the Agreement.
